Intentional Grounding

Definition

A forward pass is thrown intentionally incomplete so that the passer avoids loss of yardage or to conserve time. Exceptions Not assessed if the ball is spiked. If the quarterback has moved outside of the area between his offensive tackles (the "tackle box"), there is no foul for grounding the ball if the quarterback throws the ball past the line of scrimmage.

Outcome

10 yards or spot of foul, whichever is farther from the original line of scrimmage, and loss of down. If the foul occurs in the end zone, the play is ruled a safety.
